QV-band RF Front-End

Receive a V-band uplink signal (including multiple service signals + 1 accompanying telecommand signal) from the antenna and perform low-noise amplification. Receive signals, amplify the power to ≥ 38.5 dBm, and output to the antenna. Internal power distribution and control. Configure power supply according to operational requirements and provide agreed telemetry data. Switching and telemetry functions. The solid-state amplifier includes switch control. Undervoltage protection, overtemperature protection, and output overcurrent protection.
